There is a potential difference (voltage) between two points and a path for electrons to travel from an area of low potential (negative) to an area of high potential (positive). Note the direction of "current flow" is opposite the direction of electron flow. In other words current flows from positive to negative. In a circuit involving only a resistor, the current flowing in the circuit is given by I=V/R where I = current, V= voltage, and R=resistance.
What else can I help you with?
As the total resistance is reduced in a simple electrical circuit the current flow will?
increase
Where are circuits used?
Circuits are used anywhere you want to have an electrical current flow. Without a circuit, you cannot have current flow. Without current flow, you cannot do any work.
Electricity will flow only if an electrical circuit is?
if an electric circuit has potential difference. Electricity will flow only if an electrical circuit is closed.
What is the part of a circuit that connects or disconnects the circuit?
Switches, fuses and circuit breakers are examples of some of the electrical parts which can connect or disconnect a circuit to a source of current. A diode does it for alternating current, but only for one half of each cycle. "Connecting" allows an electric current to flow through the circuit. "Disconnecting" stops an electric current from flowing through the circuit.
Difference between electrical current and electrical charge?
current is the flow of charge.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
How does a resistor affect the flow of current in an electrical circuit?
A resistor restricts the flow of current in an electrical circuit by resisting the flow of electrons. This causes a decrease in the amount of current that can pass through the circuit.
How are electrical current and circuits related?
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
Do resistors limit current or voltage in an electrical circuit?
Resistors limit the flow of current in an electrical circuit.
What constitutes a complete electrical circuit?
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
What does current do in an electrical circuit?
Current is the flow of electric charge in an electrical circuit, carrying energy from a power source to the components in the circuit.
An electrical current will always flow?
An electrical current will only flow in a closed loop or circuit where there is a complete path for the electricity to follow. If there is a break in the circuit or an open switch, the current will not flow.
Can the current be negative in an electrical circuit?
Yes, the current in an electrical circuit can be negative if it flows in the opposite direction of conventional current flow.
How do resistors affect current flow in an electrical circuit?
Resistors in an electrical circuit reduce the flow of current by impeding the movement of electrons. They create resistance, which limits the amount of current that can pass through the circuit.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
What is the function of the negative terminal in an electrical circuit?
The negative terminal in an electrical circuit serves as the point where electrons flow out of the circuit, completing the electrical circuit and allowing the flow of electric current.
What is the function of the negative anode in an electrical circuit?
The negative anode in an electrical circuit serves as the point where electrons flow out of the circuit, completing the electrical circuit and allowing for the flow of electric current.
